Law And The Sciences Of The Brain/Mind, 2016 University of Pennsylvania Law School
Law And The Sciences Of The Brain/Mind, Stephen J. Morse
This chapter is a submission to the Oxford Handbook of Law and the Regulation of Technology edited by Roger Brownsword. It considers whether the new sciences of the brain/mind, especially neuroscience and behavioral genetics, are likely to transform the law’s traditional concepts of the person, agency and responsibility. The chapter begins with a brief speculation about why so many people think these sciences will transform the law. After reviewing the law’s concepts, misguided challenges to them, and the achievements of the new sciences, the chapter confronts the claim that these sciences prove that we are really not ...
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, 2016 Northwestern Polytechnical University
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, Peican Zhu, Hamidreza Montazeri Aliabadi, Hasan Uludag, Jie Han
Pharmacy Faculty Articles and Research
The investigation of vulnerable components in a signaling pathway can contribute to development of drug therapy addressing aberrations in that pathway. Here, an original signaling pathway is derived from the published literature on breast cancer models. New stochastic logical models are then developed to analyze the vulnerability of the components in multiple signalling sub-pathways involved in this signaling cascade. The computational results are consistent with the experimental results, where the selected proteins were silenced using specific siRNAs and the viability of the cells were analyzed 72 hours after silencing. The genes elF4E and NFkB are found to have nearly no ...

Hypothesis: Cocaine irreversibly lengthens circadian period (tau), which could underlie the significant health issues of cocaine addiction. Others have reported that rewarding effects of paternal cocaine use are transgenerational. We hypothesize that the disruptive effects of cocaine on tau may also be transgenerational, causing altered subjective cocaine reward response in offspring (F1).
Methods: Male mice were exposed to cocaine-water (0.5 mg/ml) or water (control) for 6 wks. Immediately following treatment, the mice were mated with cocaine naïve dams. F1 reference for cocaine or sucrose (to test for reward specificity) was analyzed using a dual bottle (water and drug [0.15 mg/ml] or sucrose [2%]) free-choice regimen. Tau was analyzed using activity sensors with computerized data acquisition.
Results and Conclusions: Lengthened tau was evident in sires with forced cocaine compared to controls (24.18+0.17 vs. 24.07+0.02; p0.05). These data reveal that there is no transgenerational transmission of cocaine-lengthened tau in F1 males, but there was an alteration of tau in F1 females. Significantly, paternal cocaine intake significantly altered F1 preference for cocaine, but not sucrose, suggesting specificity to drug reward. Thus, cocaine addiction could involve a transgenerational paternal mode of inheritance.

Comorbidity Between Alzheimer’S Disease And Seizure Episodes, 2016 University of Colorado, Boulder
Comorbidity Between Alzheimer’S Disease And Seizure Episodes, Maryam Amini
Undergraduate Honors Theses
A mouse model of Alzheimer’s disease (AD), which overexpress the human amyloid precursor protein (APP), experience Kainic Acid (KA) induced seizures that are more severe than wild type (WT) mice. The latency and severity of seizures observed in AD mice are similar to those of Synaptophysin knockout (Syp KO) mice. Addition of amyloid plaques (Aβ) to cells in vitro leads to the breakdown of Syp-VAMP2 complex. In the present study, we investigated if the breakdown of Syp-VAMP2 complex is responsible for the observed seizure activity in AD mice. The binding of cholesterol to Syp is necessary for biogenesis ...

Robert J. Shprintzen
Velo-cardio-facial syndrome/DiGeorge syndrome, also known as 22q11.2 deletion syndrome (22q11DS) is the most common microdeletion syndrome, with an estimated incidence of 1/2,000 – 1/4,000 live births. Approximately 9–11% of patients with this disorder have an overt cleft palate (CP), but the genetic factors responsible for CP in the 22q11DS subset are unknown. The TBX1 gene, a member of the T-box transcription factor gene family, lies within the 22q11.2 region that is hemizygous in patients with 22q11DS. Inactivation of one allele of Tbx1 in the mouse does not result in CP, but inactivation of ...

The Eleanor Mann School of Nursing Undergraduate Honors Theses
Introduction: Childhood obesity is a problem that leads to many serious health effects including early maturation, decreased quality of life and increased risk for cardiovascular disease. In 2012, over one third of children were considered obese (Childhood Obesity Facts 2015). Efforts have been made to reduce this number but they have not been fully successful (Nutrition Standards for School Meals 2015, Prevalence of Childhood obesity in the United States 2011-2012 2015). What other factors are causing kids to choose foods that lead to weight gain.
Literature Review: In research regarding psychological motivations of overeating, there has been a correlation ...
Functional Analysis Of Genomic Variation And Impact On Molecular And Higher Order Phenotypes, 2015 University of Tennessee Health Science Center
Functional Analysis Of Genomic Variation And Impact On Molecular And Higher Order Phenotypes, Ashutosh Kumar Pandey
Theses and Dissertations (ETD)
Reverse genetics methods, particularly the production of gene knockouts and knockins, have revolutionized the understanding of gene function. High throughput sequencing now makes it practical to exploit reverse genetics to simultaneously study functions of thousands of normal sequence variants and spontaneous mutations that segregate in intercross and backcross progeny generated by mating completely sequenced parental lines. To evaluate this new reverse genetic method we resequenced the genome of one of the oldest inbred strains of mice—DBA/2J—the father of the large family of BXD recombinant inbred strains. We analyzed ~100X wholegenome sequence data for the DBA/2J strain ...
Plasma Micrornas Are Associated With Atrial Fibrillation (The Mirhythm Study) And Change After Catheter-Ablation, 2015 University of Massachusetts Medical School
Plasma Micrornas Are Associated With Atrial Fibrillation (The Mirhythm Study) And Change After Catheter-Ablation, David Mcmanus, Kahraman Tanriverdi, Honghuang Lin, Nada Esa, Menhel Kinno, Rosalind Lee, Divakar Mandapati, Stanley Tam, Patrick Ellinor, John Keaney, Emelia Benjamin, Victor Ambros, Jane Freedman

Background: Atrial fibrillation (AF) is the most common dysrhythmia in the U.S. and Europe. Few biomarkers exist to identify individuals at risk for AF. Cardiac microRNAs (miRNAs) have been implicated in susceptibility to AF and are detectable in the circulation. Nevertheless, data are limited on how circulating levels of miRNAs relate to AF or change over time after catheter- ablation.
Methods: In 211 miRhythm participants (112 with paroxysmal or persistent AF; 99 without AF), we quantified plasma expression of 86 miRNAs associated with cardiac remodeling or disease by high-throughput quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). We used qRT-PCR to ...
Conformational Changes And Translocation Of Tissue-Transglutaminase To The Plasma Membranes: Role In Cancer Cell Migration, 2015 University of South Carolina - Columbia
Conformational Changes And Translocation Of Tissue-Transglutaminase To The Plasma Membranes: Role In Cancer Cell Migration, Ambrish Kumar, Jianjun Hu, Holly Lavoie, Kenneth Walsh, Donald Dipette, Ugra Singh
Background Tissue-transglutaminase (TG2), a dual function G-protein, plays key roles in cell differentiation and migration. In our previous studies we reported the mechanism of TG2-induced cell differentiation. In present study, we explored the mechanism of how TG2 may be involved in cell migration. Methods To study the mechanism of TG2-mediated cell migration, we used neuroblastoma cells (SH-SY5Y) which do not express TG2, neuroblastoma cells expressing exogenous TG2 (SHYTG2), and pancreatic cancer cells which express high levels of endogenous TG2. Resveratrol, a natural compound previously shown to inhibit neuroblastoma and pancreatic cancer in the animal models, was utilized to investigate the ...
Tslp-Induced Mechanisms And Potential Therapies For Crlf2 B-Cell Acute Lymphoblastic Leukemia, 2015 Loma Linda University
Tslp-Induced Mechanisms And Potential Therapies For Crlf2 B-Cell Acute Lymphoblastic Leukemia, Olivia L. Francis
Loma Linda University Electronic Theses, Dissertations & Projects
Childhood CRLF2 B-cell Acute Lymphoblastic Leukemia (CRLF2 B-ALL) is a high-risk form of leukemia that is associated with poor patient survival outcomes. CRLF2 B-ALL is five times more prevalent in Hispanic children than others and is associated with a higher rate of relapse, thus contributing significantly to childhood cancer health disparities. This disease occurs due to alterations of the CRLF2 gene, leading to overexpression of the CRLF2 protein- a component of the receptor signaling complex for the cytokine Thymic Stromal LymphoPoietin (TSLP) on the surface of B-ALL cells. TSLP has been shown to induce proliferation of human and mouse B-cell ...

Comparison Of Next Generation Sequencing Methodology On The Ion Pgm™ System Performance Versus That On The Sanger Sequencing Method For Hv1 And Hv2 Regions Of Mtdna, 2015 University of North Texas Health Science Center at Fort Worth
Comparison Of Next Generation Sequencing Methodology On The Ion Pgm™ System Performance Versus That On The Sanger Sequencing Method For Hv1 And Hv2 Regions Of Mtdna, Wendy C. Argueta B.S.
Theses and Dissertations
Analysis of mitochondrial DNA in forensic applications has enabled the identification of a missing person through comparison with additional maternal relatives. Most forensic applications are based on sequencing of both hypervariable regions of the mtDNA. Sequencing of these regions has been commonly done using Sanger-type sequencing (STS) methodology, which is expensive, time-consuming and laborious. Next Generation Sequencing (NGS) technology, such as the Ion Torrent PGM™ System platform, overcomes most of these issues. In this study, samples from the Guatemalan population (n=40) were sequenced with both Ion Torrent PGM™ technology and STS methods. A high level of consistency (98%) was ...

UT GSBS Dissertations and Theses (Open Access)
The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular ...

Noninvasive prenatal testing (NIPT) enables the detection of common fetal aneuploidies such as trisomy 21, trisomy 18, trisomy 13, and sex chromosome abnormalities via analysis of cell-free fetal DNA circulating in maternal serum. Although the accuracy of NIPT for fetal aneuploidy is expected to be higher than that of currently available alternative maternal serum screening options, the implications of results are not straight forward. In October 2013, the option to screen for additional trisomies and select microdeletion syndromes, such as 22q11.2 deletion syndrome and 5 p- syndrome, became clinically available. Due to this rapidly evolving prenatal screening technology, clinicians ...

Correlation Matrix Analysis Identifies Gene Signatures Of Immune Cell Subsets And Their Interactions In Follicular Lymphoma, Jason R. Westin
UT GSBS Dissertations and Theses (Open Access)
There are important but ill-defined interactions between benign immune cell subsets and neoplastic B cells within follicular lymphoma (FL). Using the novel technique of correlation matrix analysis (CMA) of publicly available FL whole-tumor gene expression profiling (GEP) data, we have identified signatures of immune cell subsets. Overall survival correlated most highly with a model using signatures of macrophages, T cells, and stroma, which was able to add significantly to existing clinical prognostic tools. From our own data of a cohort of 43 FL tumors sorted into B-cell and non-B cell (NB) fractions for GEP, CMA of the tumor infiltrating NB ...
Comparative Transcriptome Analyses Of Pseudomonas Aeruginosa, 2015 Florida International University, Department of Biological Sciences
Comparative Transcriptome Analyses Of Pseudomonas Aeruginosa, Deepak Balasubramanian, Kalai Mathee
One of the hallmarks of bacterial survival is their ability to adapt rapidly to changing environmental conditions. Niche adaptation is a response to the signals received that are relayed, often to regulators that modulate gene expression. In the post-genomic era, DNA microarrays are used to study the dynamics of gene expression on a global scale. Numerous studies have used Pseudomonas aeruginosa--a Gram-negative environmental and opportunistic human pathogenic bacterium--as the model organism in whole-genome transcriptome analysis. This paper reviews the transcriptome studies that have led to immense advances in our understanding of the biology of this intractable human pathogen. Comparative analysis ...
Combination Of 16s Rrna Variable Regions Provides A Detailed Analysis Of Bacterial Community Dynamics In The Lungs Of Cystic Fibrosis Patients, 2015 Florida International University, Department of Biological Sciences
Combination Of 16s Rrna Variable Regions Provides A Detailed Analysis Of Bacterial Community Dynamics In The Lungs Of Cystic Fibrosis Patients, Melissa Doud, Michael Light, Gisela Gonzalez, Giri Narasimhan, Kalai Mathee
Chronic bronchopulmonary bacterial infections remain the most common cause of morbidity and mortality among patients with cystic fibrosis (CF). Recent community sequencing work has now shown that the bacterial community in the CF lung is polymicrobial. Identifying bacteria in the CF lung through sequencing can be costly and is not practical for many laboratories. Molecular techniques such as terminal restriction fragment length polymorphism or amplicon length heterogeneity-polymerase chain reaction (LH-PCR) can provide many laboratories with the ability to study CF bacterial communities without costly sequencing. The aim of this study was to determine if the use of LH-PCR with multiple ...
